Defensive industry
Also written Defensive industries · Defensive sector · Non-cyclical industry
An industry whose products have low income elasticity, so demand barely moves when incomes rise or fall — the workbook names food, agricultural inputs and healthcare.
In plain language
Some things people buy whether they are doing well or badly. Food is the obvious one. Medicines are another.
Demand for those products hardly changes when incomes change. Economists call that low income elasticity, and an industry built on such products is called defensive.
A defensive industry therefore feels very little of the economic cycle. A boom does not lift it much and a recession does not cut it much. What does move it is slower, one-way change in how people live — the kind of shift the workbook calls a secular trend.
How it works
Chapter 6.3 splits industries into 3 buckets by how much the economic cycle moves them, and defensive is the least affected of the 3.
The workbook's definition turns on one idea: these "are industries that create products and services that have low-income elasticity i.e., a fall or rise in income does not affect the demand significantly." Because of that, "these industries experience minimal impact on account of economic cycles."
Then comes the important qualifier. "Rather, their business prospects are affected only by secular trends." Defensive does not mean nothing happens to the industry. It means the thing that happens to it is structural rather than cyclical.
The workbook's examples. "Food, agricultural inputs, and healthcare are some of the industries that have exhibited these traits in the past." Note the tense. The workbook labels the behaviour as observed, not guaranteed.
On figures. The workbook gives no numeric test for this classification — no elasticity coefficient, no maximum permitted revenue swing. The 3 buckets are described by behaviour and illustrated by named industries, and that is all the examiner can ask for.
A worked example
Illustrative. Two Indian companies through one recession year, each starting from Rs 3,000 crore of revenue.
| Company | Industry | Revenue before | Revenue in the downturn | Change |
|---|---|---|---|---|
| A packaged foods maker | Food (defensive) | Rs 3,000 cr | Rs 2,940 cr | down 2% |
| A capital goods maker | Capital goods (deep cyclical) | Rs 3,000 cr | Rs 1,770 cr | down 41% |
Households under pressure postponed a new machine tool order. They did not postpone eating.
Now look at the same food company over 12 years rather than 1. Suppose consumers steadily shift from loose grain to branded packaged staples, and its revenue compounds to Rs 7,500 crore. That growth came from a change in habits, not from GDP — which is exactly the workbook's point that a defensive industry's prospects are driven by secular trends rather than by the cycle.
Why NISM asks about it
Chapter 6.3 (Understanding industry cyclicality) is short, entirely definitional, and therefore heavily examined. It presents defensive, semi-cyclical and deep cyclical industries together.
The standard question names an industry and asks which of the 3 buckets it belongs to. A better question quotes the definition — low income elasticity — and asks which bucket it defines. The sharpest version asks what does affect a defensive industry, where the answer the workbook wants is secular trends.
Common exam traps
- Defensive does not mean unaffected. The workbook says prospects are affected only by secular trends — so a structural shift can still reshape a defensive industry completely.
- Low income elasticity is the defining test, not low growth, not low risk and not a cheap valuation. A fast-growing healthcare company is still in a defensive industry.
- Defensive is about cyclicality, not attractiveness. An attractive industry in the workbook's sense is about competitive structure, which is a different axis entirely. A defensive industry can be structurally unattractive.
- Food, agricultural inputs and healthcare are the workbook's 3 named examples. Substituting your own list is risky when the question is drawn straight from the text.
- Do not confuse this with a defensive stock in the sense of low beta. The workbook is classifying industries by demand behaviour, not securities by price behaviour.

1.For which type of company is the Dividend Discount Model MOST suitable?
- a)Loss-making companies undergoing a turnaround
- b)Start-ups in a high growth phase
- c)Matured companies in defensive industries that pay regular and substantial dividends
- d)Companies that retain all earnings for reinvestment
Show the answer
Answer: (c) Matured companies in defensive industries that pay regular and substantial dividends
The workbook says DDM is suitable for companies that pay regular and substantial dividend, and therefore more suitable to matured companies in the defensive industry.
Option D describes exactly the situation where DDM fails — and the chapter gives the example: Alphabet Inc., the parent company of Google, has never paid a dividend. That is the whole reason the FCFE model exists as an alternative: it discounts the free cash flow available to equity shareholders instead of dividends actually paid.
Option B is wrong for a second reason too: a company in a high growth phase should not be valued on a constant growth assumption at all, because that growth is unsustainable in the long run and may even be higher than the cost of capital. Such companies need two-stage valuation.
Option A describes a company where EV/Sales is the appropriate metric — or, if no turnaround is likely, liquidation value.

- Attractive industryAn industry structure, under Porter's Five Forces, with low competition, high entry barriers and weak buyer or supplier power — letting its companies earn strong, durable margins.
- Business life cycleThe stages an industry passes through from emergence to decline — pioneering, growth, maturity, decline, and rarely reinvention — driven by the secular trends around it.
- Deep cyclical industryAn industry whose revenues swing to extremes with the economic or commodity cycle — the workbook names capital goods and steel as its examples.
- Secular trendA long-term shift in how goods or services are produced or consumed, driven by technology, regulation, demographics or lifestyle — unrelated to any single year's economic cycle.
- Semi-cyclical industryAn industry whose sales grow in economic expansions and shrink in downturns, but never below a base level of demand — sitting between defensive and deep-cyclical industries.
- Industry life cycleThe four stages an industry passes through over time — introduction, growth, maturity, and decline — each with a different pattern of sales growth and profit margin.
- Counter-cyclical businessA business whose products stay in demand, or even do better, when the broader economy is in a downturn — the opposite of one that rises and falls with the business cycle.
- Defensive and offensive strategyTwo opposite competitive strategies a company can follow — defensive, protecting its existing position from rivals, or offensive, using its strengths to actively take ground from them.
